碩士 / 國立成功大學 / 建築學系 / 88 / While the house buildings tend to higherlization and high density developing, the deck-plate floor impact vibration produced by living behaviors is becoming the important theme to residents. Domestic studies in the past on the floor impact vibration were theoretically based on impedance method. Although this method can estimate the floor impact sound easily, it cannot be fully adapted to deck-plate slabs with complicated structures and peripheral support conditions. Based on numerical analysis, this research brings up an effective, convenient method to predict floor impact vibration with various boundary conditions. Hope the method can simplify the complexity of the floor impact vibration experiment process, and provide better programs to meet the various feature of buildings in the design stage, further more, promote the residential quality of buildings.
■ Procedures
1. This research analyzes and predicts deck-plate floor impact vibration through FEM numerical analysis. And it is proved that it is accurate to find deck-plate floor impact vibration solution by comparing with measured values from an actural model.
2. After examining the accuracy of this simulation method, to draft and simulate different choices of improving the deck-plate floor vibration
■ Results of study
1. The correlation coefficient of floor vibration frequency R2=0.99, and the floor vibration spectrum radiation R2=0.90 between measured values and numerical analysis values show the accuracy of this method.
2. The thickness of materials,length-width ratio and area affect the value of vibration. Within the same impact energy, vibration of deck-plate floor will be reducing while thickness of materials,length-width ratio and area is increasing . ( predictive formula about area AP=0.0159X2-1.1379X+118.4, the R2=0.97, predictive formula about thickness of RC layer ΔAP=0.037(ΔT)2-1.2541(ΔT)-0.0029, the R2=0.99, predictive formula about thickness of steal layer ΔAP=0.0298(Δt)2-1.646(Δt)-0.3224)
3. To follow the operation process, designers and users are able to predict the impact vibration of deck-plate floor established on actural boundary condition.
